trace

Log a message at the TRACE level according to the specified format
and arguments.

This form avoids superfluous string concatenation when the logger
is disabled for the TRACE level. However, this variant incurs the hidden
(and relatively small) cost of creating an Object[] before invoking the method,
even if this logger is disabled for TRACE. The variants taking one and
two arguments exist solely in order to avoid this hidden cost.

debug

Log a message at the DEBUG level according to the specified format
and arguments.

This form avoids superfluous string concatenation when the logger
is disabled for the DEBUG level. However, this variant incurs the hidden
(and relatively small) cost of creating an Object[] before invoking the method,
even if this logger is disabled for DEBUG. The variants taking
one and two
arguments exist solely in order to avoid this hidden cost.

info

Log a message at the INFO level according to the specified format
and arguments.

This form avoids superfluous string concatenation when the logger
is disabled for the INFO level. However, this variant incurs the hidden
(and relatively small) cost of creating an Object[] before invoking the method,
even if this logger is disabled for INFO. The variants taking
one and two
arguments exist solely in order to avoid this hidden cost.

warn

Log a message at the WARN level according to the specified format
and arguments.

This form avoids superfluous string concatenation when the logger
is disabled for the WARN level. However, this variant incurs the hidden
(and relatively small) cost of creating an Object[] before invoking the method,
even if this logger is disabled for WARN. The variants taking
one and two
arguments exist solely in order to avoid this hidden cost.

error

Log a message at the ERROR level according to the specified format
and arguments.

This form avoids superfluous string concatenation when the logger
is disabled for the ERROR level. However, this variant incurs the hidden
(and relatively small) cost of creating an Object[] before invoking the method,
even if this logger is disabled for ERROR. The variants taking
one and two
arguments exist solely in order to avoid this hidden cost.
